Operational Characteristics for the 5” Fuel Flow Meter

 

The Flow Meter Assembly possesses the following characteristics:

  • Turbine flow meter
  • Double-walled construction to maintain structural redundancy
  • Integrated signal conditioner
  • 28 VDC nominal power input (18 – 32 VDC operating range)
  • 0.5 VDC standby voltage
  • 0.5 – 10 VDC output proportional to volumetric flow rate.
  • Mid-point calibration flow at 750 gpm generates, at the magnetic pick-up, the frequency marked on the side of the Flow Meter Assembly.
  • Outputs 5.25 VDC on J1 connector
  • Replicated output on J2 connector (raw frequency)
  • Test frequency can be input on J2 connector for isolating the signal conditioner functionality (Electrical Operation of Test Article)
  • Full scale measurement  up to 1,500 gpm
  • 0.5% FS accuracy from 130 to 1,300 gpm
  • 0.25% repeatability from 130 to 1,300 gpm
